Electrophoretic device, method for driving the same, and electronic apparatus

摘要

An electrophoretic device according to the present invention comprises electrophoretic dispersion including a liquid-phase dispersion medium and electrophoretic particles dispersed therein, in which the positions of the electrophoretic particles are controlled in accordance with an electric field applied thereto. In addition, the electrophoretic device further has a first means for applying a first voltage so that a first dispersion state of the electrophoretic particles is changed into a second dispersion state and a second means for applying a second voltage so that the second dispersion state is substantially sustained. The electrophoretic device described above has superior image-sustaining properties.
